What it does
Nim MCP Tools is an agent skill from nim-lang/vscode-nim. Use for Nim symbol navigation and diagnostics. MANDATORY: Use specialized MCP tools (nimFindSymbols, nimFindReferences, nimListSymbols, nimCheckFile, nimCheckProject) first; fall back to grep only on error or user confirmation.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Visual Studio Code. The repository describes itself as: A VS Code plugin for the Nim language.
When your agent uses it
- Nim symbol navigation and diagnostics
- Tasks that involve MCP servers
Example prompts
- “/nim-mcp-tools”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Find All References or Usages of a Symbol Name
- List All Symbols in a File
- Find Definitions
- Check a Single Nim File for Diagnostics
- Check the Current Nim Project for Diagnostics
- Standardize Naming
- Fix Project Issues
What it can do on your machine
Read from SKILL.md and the folder at commit ebe8b34. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
kindrg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nim MCP Tools loads about 2.8k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 1,576 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,576 words (~2,784 tokens).
“AI agents MUST prefer specialized MCP tools over general-purpose instruments (grep, shell commands, read_file with manual parsing) for all Nim symbol-related and Nim diagnostics tasks. This is critical for:”
